Guidance of Robot Grippers for Roof Mounting in Car Assembly Using Blue Laser Light Triangulation Laser Distance Sensors
In fully automated final assembly of passenger cars, roofs are inserted precisely into painted bodies using robot grippers. During this process, the glass roofs are gripped from a storage container and inserted with millimeter precision. Four measuring blue laser light triangulation laser distance sensors reliably position the gripper arm in relation to the body. The sensors are installed on the side of the gripper module and transmit the position to the robot control. Thanks to the blue laser light, they measure precisely on painted, glossy or dark surfaces.

Stack Height Measurement for Cookies with Blue Laser Light Triangulation Laser Distance Sensors
During the packaging of cookies in fully automated production lines, the objects are picked up by robot systems during operation and then stacked on top of each other for packaging. To ensure that the cookie stacks can be packed correctly with foil, the stack height must first be measured precisely. Blue laser light triangulation laser distance sensors measure the dark, organic cookie surfaces with high precision from above – accurately to a few tenths of a millimeter. This allows the packaging process to be readjusted and the cookies, which vary slightly in height, to be efficiently packaged.
